Application led January 8, 1908. Serial No. $9,879.

To all whom it may concern.'

Be it known that I, F REDERIGK D. GPEEN, a Vcitizen of the UnitedStates, residing at Florence, in the county of Lauderdale and State ofAlabama, have invented a new and useful food-Molding Machine, of whichthe following is a specication.

This invention relates more particularly to improvements in means forshaping irregular articles, and in one aspect, is an improvement on thestructure disclosed in a co-pending application, Serial No. 229,065,tiled Aug. 3, 1906.

One or' the primary objects of the present invention is to provide noveldriving means for the cutters, whereby t'rictional resistance is.greatly reduced, and the cutters can be driven at a very high rate ofspeed and with effective force.

Another object is to provide novel means for securing the cutters in aninoperative position during the passage of the work holding means in onedirection past the same, and for releasing said cutters to permit themto operate on the work when the holder moves in an opposite direction.

A still further and important object is to provide effective workholding means and mechanism for properly operating the same.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a top plan view of themachine. Fig. 2 is a side elevation of the same. Fig. 3 is a verticallongitudinal sectional view therethrough. Fig. a is a vertical crosssectional view on an enlarged scale. Fig. 5 is a horizontal sectionalview. Fig. 6 is a detail longitudinal sectional view through the workholder. Fig. T is a vertical cross sectional view through the same. Fig.8 is a detail perspective view of a portion of the actuating means forthe carriages. Fig. 9 is a detail vertical sectional view through one ofthe carriage holding latches. Fig. 10 is a vertical sectional viewthrough one ot the carriages, showing the driving means for a cutter.Fig. 11 is a. front elevation of the same. Fig. 12 is a rear elevation.F ig. 13 is a sectional view on the line 1313 of Fig. 6. Fig. 14C is adetail sectional view on the line let-111 of Fig. 6. Fig. 15 is avertical sectional view on the line 15-15 of Fig. 6.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment illustrated, a support is employed in the form of atable having a top 16 and sides 17. rThe top is provided with a centrallongitudinally disposed channel 18 in which is a wear strip 19 having aguiding groove 20. The top at one side is provided with avlongitudinally disposed upstanding track 21 and a depending track 22overhanging the upstanding track is supported by suitable standards 23secured to the table. A work and pattern -holder is employed thatcomprises aframe of angularly disposed leaves 24 and 25, the verticalleatl having rearwardly extending studs 26 secured thereto andconstituting gndgeons on which upper and lower sets of grooved rollers27 are journaled. These rollers respectively engage the under and uppersides 75 of the upper and lower tracks 21 and 22. Thus it will beobserved that the frame is capable of a reciprocatory movementlongitudinally over the table top. The outstanding or overhangingportion 25 terminates in a clamping bar 2S that is provided with alongitudinally disposed T-shaped groove 29 opening through one side ofthe bar. From this bar is adjustably suspended the pattern holding meansand work clamping devices. 85

As shown, particularly in Figs. 6, 13, 1a and 15, hangers 30 have theirupper ends located against the outer face of the bar 28, and are securedthereto by bolts 31 having heads 32 located in the slot 29. Thesehangers carry at their lower ends diamond shaped guides 33, the outer'ends of which are tapered, the inner ends being provided with work andpattern receiving sockets 34. Said guides also are preferably providedon their under sides with ribs 35 that move in the groove or channel 20.lVork clamping devices are also secured to the bar 2S. As shown,particularly in Figs. 6 and 7, these devices, each compris-e a head 36located against the outer tace of the bar and adjustably fastened tosaid bar by bolts 37 having heads engaged in the slot 29. Vertical workengaging pins 3S are slidably mounted in the heads, and have outstandingpins 39 engaged by eccentrics 40 rotatably mounted in recesses #llformed in the heads and having offset handles i2. It will be understoodthat as many of these clamping devices may b-e employed, as desiredA Thepatterns, one of which is shown at lf3, are placed betwee the guidingdevices 33 with their ends located in the sockets 3i, and these patternsfurthermore have longitudinal ribs el on their under sides that slidablyengage in the guiding groove or channel 20. The work to be shaped, isplaced upon the pattern, as indicated in dotted lines in Fig. G, and isclamped by the pins 3S, the eccentrics en() being rotated to raise andlower said pins, and thus clamp the work in place.

For the purpose of reciprocating the work holder, the followingmechanism is preferably employed. main driving shaft is journaled uponone end of the frame, and carries a friction wheel 4G. A countershaftl?, journaled in the table, is belted, as shown at t8 to said maindriving shaft. This countershaft has a friction wheel 9. rn idler 50,journaled on a stud on the frame of the machine, is engaged with thewheel i6, and between the wheel i9 and the idler 50 is located afriction wheel 5l carried by a shaft The end of the shaft that carriesthe friction wheel 5l is journaled in an eccentric bearing and thiseccentric bearing as shown in Fig. 2, is provided with a depending armas having a link connection 5s with a crank arm 55 on a roel; shaft 5G.The rock shaft is located at the opposite end of the machine and isprovided with an upstanding hand lever 5T. Tt will thus be evident thatby operating the lever 5T, the eccentric bearing 53 may be turned sothat the friction wheel 5l can be carried into engagement either withthe friction wheel 49 or the idler 50. Thus said friction wheel 5l, andconsequently the shaft 52 can be driven in opposite directions and atdiffer-ent speeds. Now the shaft 52 is provided at the end opposite thewheel 5l with a pinion 58, and this pinion is in mesh with a gear wheel59 carried by another shaft GO. The latter shaft is provided at itsopposite end with a drum Gl, and wrapped upon said drum is a cable 62.The cable has opposite stretches 63 extending around idlers G-l at theends of the table, and the end portion of these opposite stretches aredisposed in overlapping relation, and secured at their ends and atseparated points to the table, as shown at in Fig. 2. lWith thisarrangen'ient, it will be evident that by operating the lever thereforethe drum can be rotated in opposite directions, and the cable thus drawnin opposite directions. This therefore will cause the reciprocation ofthe work carrier, its

movement in one direction being at a greater speed than its movement inan opposite direction.

A plurality of driving shafts, preferably four or more are journaled inthe table transversely beneath the top, and are designated titi. Theseshafts are rotated in opposite. directions by suitable belts GToperating around pulleys (38 on the main driving shaft 45 and aroundother pulleys 69 on said driving shafts. Associated with each of thedriving shafts 6G is a pair of carriages, said carriages beingdesignated 70. The carriages are movable longitudinally of the shafts(3G, and consequently toward and from the path of movement of the workcarrier. They are in the form of upright frames, their lower ends havingguide-ways 'Tl operating on transversely disposed fixed guides T2secured to the lower portion of the table. The upper ends of thecarriages of each pair are located between and engage a pair oftransversely disposed guide rods 723 that arc :apable of reciprocation,and are slidabl'v mounted, as shown at 7% in the sides l? of the table.One of the carriages is fastened, as shown at to one of the guides, andconsequently slides on the other, while the other carriage is fastenedto said other guide and slides on the first mentioned guide.

Journaled on each carriage is an upright countershaft 7G that projectsthrough an opening T7 in the top 1G of the table, and carries at itsupper end a suitable cutter head T8. The lower end of each countershafthas a beveled friction gear T9 that cooperates with another frictiongear SO slidably mounted on the adjacent drive shaft 6G. The detailconstruction of this gearing shown more particularly in Figs. l0, ll andl2. Tt will be observed that the gear wheel S0 is provided with a head8l having opposite slots 82 that register with corresponding slots S3formed in the shaft (36. The wheel is feathered to the shaft, and thefeather consists of sets of balls Sel. located in the registered slots,and thus prevent the relative rotation of the shaft and wheel or gearwhile permitting the longitudinal movement of the latter upon theformer. Thus each drive gear 8O is movable longitudinally with thecarriage, and it also is capable of a limited movement with respectthereto. To this end, coiled springs S5 are seated in sockets 8G formedin the hub of the wheel 80 and gear against a plate 87 constituting oneof the end plates of a ball bearing, said ball bearing also havinganother end. plate SS and a ball cage S9 in which an annular series ofballs 90 are located. This ball bearing is interposed between the wheelyS0 and the adjacent portion of the frame, and the springs S5 bearagainst one side of the same, as shown in Fig. 10. A tension varyingdevice, in the form of a nut 91, bears against the opposite side of theball bearing, and is threaded upon a stem or sleeve 92 that is screwedinto the carriage, and constitutes the bearing for the shaft 66. lt willbe observed that by this arrangement, the

tact, and the tension of said springs can be varied by screwing the nut91 in one direc-.

tion or the other, so that wear may be taken up and the properfrictional engagement at all times maintained without materialfrictional resistance. Eor the purpose of urging the carriages andconsequently the cutters toward the work holder, bell cranks areemployed that are connected to said carriages.

As illustrated in Figs. 4 and S, rock shafts 93 are employed havinginwardly extending arms 94 on which Weights 95 are adjustably mounted.The rock shafts also have upstanding arms 96 connected by links 97 withcertain of the carriages. These rock shafts also constitute supports forrock sleeves 9S that are journaled thereon, and have inwardly extendingarms 99 provided with weights 100, the sleeves being provided withupstanding arms 101 that are connected by links 102 with other of thecarriages. rihus the weights serve to urge the carriages and cuttersinwardly toward the center of the table, and if desired, springs 103 mayalso be employed for moving said carriages inwardly. rlhe positions ofthe cutters and carriages are, however', cont-rolled by the pattern ortemplet, as is well understood, and for this purpose rollers 104C arejournaled on upstanding portions of the carriages, and are located onopposite sides of the work holder, these rollers being disposed atdifferent heights, as illustrated in Fig. 3, in order that they willengage diierentportions of the pattern.

In order to hold the carriages `in their outermost positions with thecutters out of action, locking mechanism is employed, preferablyconstructed as follows. The guide rods 73 of each pair are provided inone end with a notch, seat or shoulder 105, and a vertically movablelatch 10G, shown in Fig. 9, has a cross head 107 that engages in bothnotches or seats. The latch is urged upwardly by a spring 10S, thetension of which may be varied by a screw 109 bearing against its lowerend. The notches 105 are so located that the cross head 107- will engagetherein when the carriages have been forced to their outermost positionsby the widest portions of the diamond shaped guides 33. The latches areautomatically operated, however, to release the carriages, and to thisend, said latches are provided with upwardly extending stems 110 uponwhich the lower arms 111 of bell cranks 112 bear. rhese bell cranks arepivoted on the table top, and have upstanding arms 113.

A swinging actuating device 1111 is pivoted upon the rear side of thereciprocating work carrier frame, and the upstanding arms 113 arelocated in the path of movement of the lower end of this device, as willbe evident springs 85 hold the gears 1n frictional conby reference toFig. 2. The device 114 is capable of free swinging movement in onedirection, but it is held against swinging movement beyond a verticalposition in an opposite direction by a stop pin 115. Thus it will beevident that when the work carrier moves in one direction, t-heactuating device 11st will swing freely over the upstanding arms 113 ofthe bell cranks, but when moved in an opposite direction, it will causesaid bell cranks to move downwardly, thus successively depressing thelatches and releasing the guides 73 therefrom. The guides beingreleased, the carriages will move inwardly under the' action of theweights 95 and 100,'as will be evident.

W ith the above description of the structure, Vthe operation issubstantially as follows. Properly shaped cutters having been secured tothe cutter heads, the desired pattern is placed in position, and thework to be operated upon, is secured in the holder, said holder beinglocated at one end of the machine. The operator then swings the lever 57to a position to cause' the drum 61 to be rot-ated at the slower or feedspeed. rEhe carriages are locked in their outermost positions, but asthe work holder progresses through the machine, the actuating device114k will successively operate the latches to release said carriage.Immediately their weights or the weight and springs together will causethe carriages to move inwardly and guided by the rollers 104 operatedagainst the pattern, the cutters will vbe permitted to operate upon thework or held out of engagement therewith, accordingly as the differentcuts are to be made. Thus in the present embodiment, the machine isdesigned to operate on wagon hounds and straight and concaved cuttersare therefore employed. A pair of straight cutters, rotating in onedirection, are allowed to come into operation, as long as they will cutwith the grain, but as soon as the curve changes to bring them againstthe grain,^they are moved outwardly by the pattern, and the opposite setof rotating straight cutters moves into action. In like manner, theoppositely rotating concaved cutters are allowed to move into operationas long as they will cut with the grain. It will therefore be seen thatthe article is completely shaped during its passage through the machine,and that but one machine is required. In actual practice, it has beenfound entirely practicable to clamp two hounds, and operate upon themsuccessively during the passage of the work holder once through themachine. As Ysaid work holder reaches the opposite end of the machine,the rollers 104, engaging the rear diamond shaped guide are forcedoutwardly, thus moving said carriages outwardly to a position to permitthe latches to rengage the guide rods 73 and relock said carriages intheir outermost positions. Then this has occurred, the operator re-Verses the lever 57, thereby reversing the direction of rotation of thedrum 61, and causing the work holder to return at a greater rate ofspeed. During this return movement, the actuating device 114 passes idlyover the arms 113 of thc bell cranks 112, and the latches will thereforenot be operated. Then the front end of the machine is again reached, thelever 5T is thrown into an intermediate position, which stops thecarriage, permitting the finished work to be removed and a new piece tobe positioned.

From the foregoing, it is thought that the construction, operation, andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be restored to without departing fromthe spirit or sacrificing any of the advantages of the invention.
